About OTF
OTF
OTF (OpenType Font) is a scalable font format jointly developed by Microsoft and Adobe, extending TrueType with support for PostScript (CFF) glyph outlines, advanced typographic features (ligatures, alternates, small caps), and large character sets using Unicode. OTF is the modern standard for professional typography and is supported by all major operating systems and design software.

Frequently Asked Questions
What is an OTF file?▼
OTF (OpenType Font) is the modern font standard, supporting advanced features like ligatures, stylistic alternates, and multiple writing systems. It is preferred by designers for its richer typography.
Why convert OTF to WOFF2?▼
For web use. WOFF2 is compressed for fast browser loading — roughly 70% smaller than OTF. Keep the OTF for desktop installation and the WOFF2 for serving online.
OTF vs TTF — what is the difference?▼
OTF (OpenType with PostScript outlines) often supports richer typography and cleaner rendering at small sizes. TTF (TrueType) is older and universally compatible. Most modern apps handle both.
Can I convert a font to embed on a website?▼
Yes — convert to WOFF or WOFF2, the browser-only formats designed for web typography. They keep the glyph quality while shrinking file size for fast loading.
Are my fonts private when converting?▼
Completely. Conversion happens locally in your browser — licensed and custom fonts never leave your device.
